I happen to disagree. From my experience as the maintainer of PCRE for z/OS, most installations that I have encountered use IBM037, regardless of what IBM wants you to believe. And BTW, this includes my test bed, which is a bona fide system rented from IBM.Zeev Atlas

I propose commenting out the code that generates the tables for these two code pages until and if someone actually wants to use them. The underlying code has changed so that only one place has to change to accomplish this, and to reverse it should the need arise. By not generating the tables, we speed up some regens when needed, and the disk space used in the distribution is smaller.
